跨ぎ動作における足部位置に関する研究

抄録

The purpose of this study was to investigate the toe-distance and heel-distance for young people stepping over an obstacle on a dual-task condition. Subject characteristics were as follows: age range 21-22 years, height range 154-180 cm, and step range 31-67 cm. The experiment was performed in a large room with a straight 8 m travel path available for the subjects to walk along. Test conditions were as follows: double obstacles at 2cm and 2cm (C1), 5cm and 5cm (C2), 10cm and 10cm (C3), 30cm and 30cm (C4), 2cm and 10cm (C5), 2cm and 30cm (C6), 10cm and 2cm (C7), and 30cm and 2cm (C8) positions. The distance between the obstacles were 2steps of each subject. As a result of this study, step over the motion of dual task has the characteristics of toe-distance and heel distance. Therefore, it was shown that second obstacle has influenced the toe-distance and heel distance.
